The determination of bunch features that are relevant for bunch weight estimation is an important step in automatic vineyard yield estimation using image analysis. The conversion of 2D image features into mass can be highly dependent on grapevine cultivar, as the bunch morphology varies greatly. This paper aims to explore the relationships between bunch weight and bunch features obtained from image analysis considering a multicultivar approach.
Innovation processes in rural contexts occur in systems that are diverse, coupled with complex challenges. Dealing with complex systems requires an understanding of the social dynamics of actor networks and innovation.This study attempted to provide insights on thecompositional dynamics of actor networks,and how they influenceinteractive learning and innovation among agro-processing enterprises in South Africa. The guiding research questions to help address the study objectives are:What are the structural characteristics of actor networks for innovation in rural contexts?
Pour accompagner les efforts d’adaptation au changement climatique couplé à la rareté des ressources en eau et promouvoir une agriculture durable à forte valeur ajoutée, la TIL est l'un des moyens les plus significatifs pour améliorer la productivité de l'eau en agriculture. Au Maroc, En dépit des efforts et incitations financières pour accélérer l’adoption de la TIL, les superficies actuellement équipées de cette technologie ne représentent qu'une part négligeable du potentiel.
The study explored the contribution of information and communication technology (ICT)-based information sources to market participation among smallholder livestock farmers. Use of ICTs is considered paramount for providing smallholder farmers with required market information, and also to reduce market asymmetries. A double hurdle regression was utilized to analyze data collected from 150 smallholder livestock farmers in the study area.
Literature is scanty on how public agricultural investments can help reducing the impact of future challenges such as climate change and population pressure on national economies. The objective of this study is to assess the medium and long-term effects of alternative agricultural research and development investment scenarios on male and female employment in 14 African countries. The authors first estimate the effects of agricultural investment scenarios on the overall GDP growth of a given country using partial and general equilibrium models.
This brief is part of the series, A Field Guide for Disaster Risk Reduction in Southern Africa: Key Practices for DRR Implementers, coordinated by the FAO Subregional Office for Disaster Risk Reduction/Management for Southern Africa. The brief provides practical guidelines on storage practices and methodologies to assist southern African farmers prone to natural hazards, mainly cyclones, droughts and floods.
Pour répondre à la montée en puissance des enjeux environnementaux, le monde agricole met en œuvre des dispositifs agri-environnementaux (AE) à destination des agriculteurs afin d’en orienter les pratiques.
This publication aims to inform the debate on the status of food security in Arab countries, and provide policy options for enhancing food security in the future, in line with the overarching directions of the 2030 Agenda for Sustainable Development. Given the heterogeneity of the Arab region, both in terms of natural endowment, particularly in water resources, and economic capabilities, the report’s analysis divides the region into four subregions, each consisting of a more homogeneous group of countries.
This book documents a unique series of 19 case studies where agricultural biotechnologies were used to serve the needs of smallholders in developing countries. They cover different regions, production systems, species and underlying socio-economic conditions in the crop (seven case studies), livestock (seven) and aquaculture/fisheries (five) sectors. Most of the case studies involve a single crop, livestock or fish species and a single biotechnology.
Over the last 10 years much has been written about the role of the private sector as part of a more widely-conceived notion of agricultural sector capacity for innovation and development. This paper discusses the emergence of a new class of private enterprise in East Africa that would seem to have an important role in efforts to tackle poverty reduction and food security. These organisations appear to occupy a niche that sits between mainstream for-profit enterprises and the developmental activities of government programmes, NGOs and development projects.
